VALVE FOR WATE RCLOS ETS.

SPECIFICATION forming part of Letters VPatent'. No. 352.643, dated November 16, 1886.

Application led June 14, 1886.

To all whom it may concern:

Be it known that I, JOHN DEMAREsT, of the city, county, and State of N ew York, have invented a new and useful Improvement in q Valves for Vater-Olosct's, of which the following is a specification.

My present invention relates to a Watercloset valve adapted for use in closets such as are described and shown in Letters Patent heretofore granted to me, No. 195,705, October 2,' 1877, and No. 199,418, January 22, 1878.

The special object of this invention is to vary the Water-supply according to the pressure of Water Without the necessity of changing the valve-case or attachments to the closet and to facilitate the connections of the waterpipes. i

In the drawings, Figure l is a vertical section transversely of the valve-chamber, and Fig. 2 is a plan of the valve.

The valve-chamber a, pipe b, cover c, cylindrical portion c to the cover, cup d, rod and handle e, cylinderf, and its damf, the lever g, and float h are all similar to the parts shown and described in my aforesaid patents, and do not need further description.

The valve-case t' is composed of a hollow cast-metal body through which passes a right'- angled waterchannel, i. The base of the valve-caser passes through the shell of the valve-chamber and is securely held by a nut, k, and the upper portion of the valve-case 'i passes through the side casing of the valvechamber a, and the joint at a is made tight with Washers, or in any other desired manner.

The supply-water pipe l is connected to a removable tubular plug, m, which plug is screwed into the base of the valve-case t', and the upper surface of said plug is conical to Serial No. 205,060. (No model.)

form a valve-seat, the hole through the plug 4o being varied in size in dierent plugs to adapt the valve to use in places having different water-pressures. The flushing-pipe n is connected to the screw end n of the valve-case i, and said pipe n leads to and is connected with the water-closet bowl.

The spindle o passes through the body of the valve, and the upper end is slotted for the end ofthe lever g, Which lever is pivoted by the screw r in lugs r' upon the side of the 5o valve t'. "Ihe lower end of the spindle o forms the valve, and it is recessed to receive the disk o', of elastic material, and said spindle is made with a ang'e, o2, which takes a bearing and forms a valve against the seat t when the spindle is raised by thedioat h falling. When the float is raised, the stem is depressed and the disk o rests upon the conical end of the plug m and shuts off the supply of water.

I claim as my invention- In an automatic water closet valve, the valve-case having a flange and nut for clamping to the valve-chamber, and an inlet at the lower end, and a lateral discharge-pipeat one side, in combinationwith aflat valve, a cylindrical stein sliding in the upper part of the valvecase, and a lever and float for the same, and a valve-seat having an exterior conicalsurface at the top and screwed into the lower end of the valve-case, so as to be changeable to 7o adapt the valve to different pressures of water, substantially as specified.

Signed by me this 9th day of June, A. D. 1886.

JOHN DEMAREST.
